I don't know if this will help or just confuse you more, but I had the 8.8 in my Cobra that I sold and had it beefed up with an Eaton Posi and it stood up to the 500+ horse for many years. It was a 4 link. In the Coupe I have the 8.8 with Eaton posi and IRS. The IRS is better on the road course, but both worked great.
I believe there is some company that I have seen that will make you a 9" housing that is already shortened to fit your car but can't remember where I saw their add. I believe it was in one of the Hot Rod boos but am not certain.
